Can u provide formula for calculation where is speed of ship and signature and how its effect on chance to hit ship and if its hit how much damage will be reduced thank you ---

## Missile damage formula The equation for missile damage is as follows: [![MissileDamageFormula.png](https://global.discourse-cdn.com/eveonline/original/3X/8/5/85cd61e0cb9e8ef993fec7daafc6c0d5e33a1135.png)](https://wiki.eveuniversity.org/File:MissileDamageFormula.png) Here are the terms in the equation. Except for the “damage reduction factor”, these are the same as were defined in the [Basic Picture](https://wiki.eveuniversity.org/Missile_mechanics#The_Basic_Picture) section, above : | S | signature radius of target | _Note: The bigger the better_ | | --- | --- | --- | | Vt | velocity of target | _Note: The smaller the better_ | | D | base damage of missile | _Note: The bigger the better_ | | E | explosion radius of missile | _Note: The smaller the better_ | | Ve | explosion velocity of missile | _Note: The bigger the better_ | | drf | damage reduction factor | _Note: The smaller the better_ | [https://wiki.eveuniversity.org/Missile\_mechanics](https://wiki.eveuniversity.org/Missile_mechanics) ---

is there for turrets? ---

Yep, it’s all listed in the [Eve Uni wiki.](https://forums.eveonline.com/uploads/short-url/pKA7KpPUHgfWU2AtbJ6dk2iEmKt.png) ## Hit Math A turret’s chance to hit a target is calculated using the equation below. It will produce a result between 0 and 1, representing a probability between 0% and 100%. This value is then compared to a random number between 0 and 1. If the random number is greater than the calculated result, the turret misses. **Note: The entire expression contained within the outermost set of parentheses is an exponent.** [![Turret hit chance.png](https://global.discourse-cdn.com/eveonline/original/3X/b/4/b47a5f2bfef28b7c5d71052ee4e9b5a81a2b83b9.png)](https://wiki.eveuniversity.org/File:Turret_hit_chance.png) _Angular_ is the [angular velocity](https://wiki.eveuniversity.org/Angular_Velocity) (movement between the attacker and the target expressed as an angle in radians per second). _Tracking_ is the turret’s tracking value (listed on the info window and means how well the turret can hit a moving target). _Signature_ is the target signature radius (aka target size, a big target is easier to track). _Distance_ is the range in meters. _Optimal_ is the optimal range of the turret. _Falloff_ is the falloff range of the turret.

Do you have the align/warp equations as well? 😃 ---
